Ok guys, this is a strange problem. I don't see how it makes sense.. but yea. When I plug my guitar into my buddies amp (60w fender Rumble) he plays nice tone works now so does volume.. but it's dual input so when he plugs in my bass gets REALLY quiet. Also his amp came with red LEDs on the bottom, and when you hit the strings they flash brighter.. when I do it they don't flash..It is as if the amp isn't getting enough power from the guitar but that kinda doesn't make sense to me, unless the pups are battery operated. I think the pups are good because the sound that comes from this bass is sweet! Any ideas? Thanks for your help guys! and keep on rockin'
